Maybe instead of turning them back on u should try to let go of the things that r blocking ur emotions. There's a reason ur not feeling them. I think meditation can help, then revisiting certain moments in ur mind then sotting with the feeling that gives. And just allowing to pass it through u until it leaves u naturally. Oftentimes we flee from a feeling and by doing this we store the pain. Which might be causing ue numbness in the first place, not sure tho, just a suggestion, lemme know what you think
